Hi,
The Open MPI potentially uses WMI to launch remote processes, so the WMI
has to be configured correctly. There are two links talking about how to
set it up in README.WINDOWS file:
http://msdn.microsoft.com/en-us/library/aa393266(VS.85).aspx
http://community.spiceworks.com/topic/578
For testing whether it works or not, you can use following command:
wmic /node:remote_node_ip process call create notepad.exe
then log onto the other Windows, check in the task manager if the
notepad.exe process is created (don't forget to delete it afterwards).
If that works, this command will also work:
mpirun -np 2 -host host1 host2 notepad.exe
Please try to run the above two test commands, if they all works you
application should also work. Just let me know if you have any question
or trouble with that.

Hi,
I'm trying to run an MPI code using processes on a remote machine.
I've connected the 2 machines using a crossover cable and they are
communicating with each other(I'm getting ping replies and I can
access drives on one another).
When I run mpiexec --host /system_name/ MPI_Test.exe, I get the
following error:
C:\OpenMPI\openmpi-1.6\build\Debug>mpiexec -host SOUMIWHP4500449
MPI_Test.exe

Could anyone tell me what I'm missing?
I've configured MPI on VS Express 2010 and I'm able to run MPI
programs on one system.
On the other computer, I pasted the MPI_Test.exe file in the same
location as the calling computer.
Thanks,
Vimal
